Embodiment Construction

[0038] As mentioned in the background technology section, in the prior art, after the OLED display panel is manufactured to form an electronic client, the image compensation effect is not good in the actual use process.

[0039] The inventors have found that the problem of the above phenomenon is:

[0040] Such as figure 1 As shown, it is a schematic diagram of the compensation structure of the OLED display device in the prior art; it includes Flash011 located on the main FPC (flexible circuit board) 01 of the electronic client P for storing compensation data; the display located outside the electronic client P The display compensation value random access memory (De-Mura RAM) 021 in the driver chip (Driver IC) 02, the corresponding display compensation value logic unit (De-Mura Logic Elements) 022, and the display image data random access memory (Display RAM) 023 and Other Logic Elements (Other Logic Elements) 024. Such as figure 2 Shown is the data flow diagram of the OLE...

Abstract

The application provides an OLED display device, a compensation data power-on transmission method, and an image display method. By setting the display compensation value random access memory and the display compensation logic unit in the drive chip on the electronic client, and electrically connecting each structure In the stage of power-on and non-display, the compensation data is stored in the display compensation value RAM of the electronic client, and the image is compensated by the display compensation logic unit of the electronic client. Since the display compensation value random access memory and the display compensation logic unit are set on the electronic client, it does not occupy the area of ​​the driver chip, there is no need to increase the area of ​​the driver chip, and there is no problem of distortion; and there is no need to erase the original data for different Frame rate switching, no black screen time, better image display and better user experience; directly calling the compensation data corresponding to different frame rates can ensure the accuracy of compensation and make the compensation effect better.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an OLED display device, a compensation data power-on transmission method, and an image display method. Background technique [0002] At present, Active Matrix Driving OLED (AMOLED for short) has the advantages of self-illumination, high display contrast, thin thickness, wide viewing angle, fast response speed, wide operating temperature range, simple structure and manufacturing process, etc. properties are widely used. However, the current of the organic light-emitting diode will vary with the shift of the threshold voltage of the driving transistor, so that the AMOLED display panel will have non-uniform display brightness Mura (color spot defect). The Mura phenomenon means that the actual brightness of some pixels is darker or brighter than the theoretical brightness that should be displayed, which in turn affects the brightness uniformity and brightness constancy of the AMOED...
